摘要
本文应用普朗特混合长理论导出的属性输送通量密度的交换公式,引进布德柯和拉依赫特曼湍流系数模式,从而导出不同形式的大气尘埃或污染物含量垂直分布表达式.分析认为:任意层结下的湍流系数随高度线性增加时,大气尘埃或污染物平均含量(?)随高度呈幂指数变化;若湍流系数随高度呈幂指数变化时,大气尘埃或污染物平均含量(?)随高度呈ε次幂变化.
In this chapter an exchange equation of the flex density for the attribute transmission is infer-
red from using the Prandtl Mixing Length Theory and then an expression of vertical distribution
on the lower layer of pollutants as well as atmospheric dust in different forms is inferred from in-
troducing the turbulent coefficient models of both Д·Л LAYIHETE MAN and M·И·
BUDEK.By analyses it is considered that the average content (?) of atomspheric dust or
pollutants varies with the height showing a variation of the exponent sign as the turbulent
coefficient under the arbitrary sandwich increases with the height linearity;and the average con-
tent (?) of atmospheric dust or pollutants will show ε subpower relation with the distribution of
height if the turbulent coefficient is showing the variation of the exponent sign with the variation
of height.
